The Accomplishment of the Phenomenon of Perfect Optical Cloaking Using A Multi-Lens System

Different cloaking technologies exist but have not yet been practically applicable as a phenomenon in itself and a wide variety of applications owing to the treatment of the phenomenon initially with a mathematical approach, hence turning the interesting phenomenon into a boring, cumbersome and an impractical one by neglecting the feasibilities involved at a particular yet crucial stage. This paper discusses the phenomenon of paraxial ray optical cloaking with a practical approach, void of heavy mathematical equations. The technique elaborated in this paper is not dependent upon the distance between the pairs of lenses since lenses with the same focal lengths have been used in the experiment, contrary to which was done in prior researches and experiments. It is noted that the perfect paraxial optical ray cloaking is observed at a very low cost when compared to other experimental setups. This low cost helps in setting up experiments for the education sector. The experiments for the achievement of the invisibility can be performed by students of even secondary and higher secondary standards due to the affordability. However, it is also observed that this experimental setup is currently not applicable for hiding or 'cloaking' objects larger in size, but larger objects can be hidden or 'cloaked' if the diameter of the lenses is increased.
